"From Red Hat Security Advisory 2010:1003 :

Updated git packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

Git is a fast, scalable, distributed revision control system.

A cross-site scripting (XSS) flaw was found in gitweb, a simple web
interface for Git repositories. A remote attacker could perform an XSS
attack against victims by tricking them into visiting a specially
crafted gitweb URL. (CVE-2010-3906)

All gitweb users should upgrade to these updated packages, which
contain a backported patch to correct this issue.");
